Filed: 1921-11-15
Abstract: 192,804. Lytton, E. Nov. 15, 1921. Clutches, friction.-In contracting-band friction clutches, of the kind in which the band is secured at one end to a driving or driven casing or hollow fly-wheel, and at the other end to an arm or pin passing through a slot in the casing and actuated by a lever, which is pivoted to the casing and is acted on, directly or throughthe intermediary of other moving parts, by a sliding collar, this collar has a coned operating-surface. In one form, Fig. 3, applicable where the driving-shaft 1 is subject to reversal, the drum 2, which may be covered with friction material, is encircled by two oppositely-directed bands 14, 14<1> each secured at one end to the loose casing 4 by screws, or as shown at 15, 20. The free ends of the bands are connected respectively to arms 16, 21, traversing slots 17, 22 in the casing wall and carried by crossed levers 18, 23, which are pivoted to the outside of the casing 4 and are actuated by a sliding coned collar 12 to tighten the bands simultaneously. A similar arrangement is applicable to a single band and lever. In a modification, Fig. 6, a pin 9, passing through a slot 5 to the free end of the band 7, is carried by a bell-crank lever 34, which is actuated through an adjusting- screw 33 by a radially-sliding rod 36 bearing on the coned collar 12. This arrangement may also be duplicated.

Abstract: 818,060. Endless belt and chain conveyers. VICARS Ltd., T. & T. (Petersen Oven Co.). Oct. 27, 1955, No. 30712/55. Class 78 (1). Articles, such as pan straps 148, are transferred from an endless conveyer 12 of the slat type to an endless belt conveyer 14 arranged at an angle thereto by an endless belt conveyer 104, the width of which is less than half the width of the pan straps and the speed of which is greater than that of the conveyer 12. The pan straps fall on to the belt 14 as soon as they are carried clear of the shelf 126. The belt 104 is driven by a roller 64, which is reduced to receive it so that the surfaces of the belt and roller are flush. The upper run of the belt is supported by a flat plate to the edge of which a smooth bead 128 is welded. This bead is of the same thickness as the belt and can be replaced by a roller. An end stop 136 is adjustable longitudinally of the belt 104. The pan straps are directed on to the belt 104 by a guide 44, 52, one end of which is connected to the flange 42 of the casing by a bolt and slot 50, 48 to permit longitudinal movement and the other end of which can be adjusted with respect to the flange 40 by a rod 54. This rod has a ball-and-socket connection 56 with the guide and extends through a hole in the flange 42 and through a bushing 58 secured thereto. The rod is locked by inserting a key 60 through holes in the bushing and rod.

Title: Article comprising a resinous surface and an electrolessly formed metal layer firmly adhered to at least a portion of said surface
IPC: C08L13/00
Filed: 1976-07-23
Abstract: The mixing of at least two liquid components to give a liquid mixture which contains polyfunctional, partly ethylenically unsaturated molecules and subsequent polymerisation of the mixture gives a solid two-phase polymerisation product. The product contains a disperse solid phase containing ethylenic double bonds, by means of which this phase is oxidatively degradable, and a second continuous solid phase which is resistant to oxidative degradation and in which the first phase is dispersed. Surfaces of this material are suitable for currentless deposition of metal layers having particularly good adhesion, for example for the production of printed circuits.

Patent GB-628485-A (GB)
Title: Inhibiting the dehydrohalogenation of halogenated organic compounds
IPC: C07C17/42
Filed: 1946-10-26
Abstract: The dehydrohalogenation of halogenated organic compounds having at least one halogen atom on an aliphatic side-chain attached to an aromatic nucleus, is retarded by the addition of a minor proportion of a nitroso phenol or nitroso aromatic amine; the latter may be secondary or tertiary.  In a preferred case, the halogen compound is a chloralkyl benzene, e.g. a chloroethyl chlorobenzene or chloroethyl dichlorobenzene.  Specified nitroso compounds are: methyl phenyl nitrosoamine, nitrosodiphenylamine, p-nitrosodimethylaniline, p-nitrosodiethylaniline, and also the nitroso compounds of phenol, thymol, cresols, xylenols, naphthols, and the halo-substituted phenols, e.g. o-chlorophenol and 2 : 5-dichlorophenol.  The nitroso phenols and amines may be substituted by carboxyl or carbalkoxyl groups, e.g. as in methyl nitrososalicyate, acyl groups, e.g. as in nitrosohydroxyacetophenone and nitrosoacetanilide, and alkoxyl groups, e.g. as in nitrosocatechol monomethyl ether.  The type of inhibitor is chosen to fit the method of use, e.g. for bulk storage or the distillation of the halo-compound.  In the latter case two inhibitors may be used, one of higher and one of lower boiling point than the compound to be distilled.  In the examples, there is shown the influence of a -nitroso-b -naphthol, p-nitrosodimethylaniline, methyl phenyl nitrosoamine, diphenylnitrosoamine, p-nitrosophenol, nitrosothymol, nitrosonaphthol, and p-nitrosoaniline, on the stability of chloroethyl dichlorobenzene.  The experiments are conducted in the presence and absence of powdered copper, "Monel" metal (Registered Trade Mark), and stainless steel, and in one case in the presence of styrene.  In other examples, p-nitrosodimethylaniline is used to stabilize pentachloroethane, and bromoethyl dichlorobenzene is stabilized with a -nitroso b -naphthol and with p-nitrosodimethyl-aniline.
